Abstract:
A method for monitoring stitching between two adjacent printheads includes capturing one or more images of content printed on a moving print media in at least a stitch boundary or overlap region to obtain pixel data. The pixel data is then averaged in a media transport direction to produce blur in an image or images. Derivative data of the averaged pixel data is determined and one or more peaks is detected in the derivative data. A type of stitching artifact is determined based on the detected peak in the derivative data.
